CONDAIR STRIKES A CHORD WITH FORTH PIPE ORGANS


orth Pipe Organs, a specialist pipe organ builder, restorer and maintainer, has been incorporating Condair humidifiers into its projects for over 20 years. Serving a range of clients from large-scale


performance venues, such as Edinburgh University’s McEwan Hall, to schools and church organs around the country, it helps protect instruments from the dangers of dry air, ensuring they remain mechanically stable and tonally consistent. David Page, Director at Forth Pipe Organs, comments, “Pipe organs are


constantly reacting to the air around them. When humidity drops too low, timber components move, leather parts stiffen and tuning stability suffers. Maintaining relative humidity between 40% and 50% is essential for protecting their long-term integrity and performance.” David continues, “What’s important for us in choosing a humidifier partner is having confidence that


they understand the application and that the solution genuinely fits the environment we’re working in. Condair’s range gives us that flexibility. Whether we’re dealing with a large performance venue or a much smaller, more challenging space, Condair’s humidifiers and application advice always help us find the right humidity solution. This allows us to focus on the organ itself, knowing the environmental conditions are being properly managed.” Steve Hale, Special Projects Contractor for Condair, comments, “It’s been a great pleasure to work with


David and his team at Forth Pipe Organs for so many years. They operate across a wide variety of organs, and each environment presents different challenges. In large venues with central air handling systems, humidification is often integrated into the ventilation system, allowing moisture to be evenly distributed throughout the space. This approach helps stabilise humidity levels around the organ without affecting the visual character of the building, which is particularly important in heritage settings. “By contrast, many church installations and enclosed organ chambers require more localised humidity


control. In these situations, compact steam humidifiers with fan-assisted distribution can be positioned close to, or even inside, the instrument, delivering targeted humidification directly to sensitive components. This provides effective protection even where no central ventilation system exists or where heating is used only intermittently.” Steve concludes, “When selecting the most appropriate humidification solution for a pipe organ


project, it’s important to consider not just the size of the space, but how air moves through it and within the organ itself. Ensuring balanced humidity throughout the internals of the organ, rather than in just one area, is critical.” Forth Pipe Organs offers a comprehensive range of services, including design, restoration, tuning


and ongoing maintenance of pipe organs. Its dedicated staff of skilled personnel has over 200 years’ collective experience. Condair Group is the world’s leading specialist in humidity control and evaporative cooling, with


energy-efficient, hygienic and innovative technologies for commercial, industrial and heritage applications. The company has production sites in Europe, North America and China, its own sales and service organisations in 23 countries, and representatives in 50 locations worldwide.

Ideal Commercial Heating hybrid system delivers efficient, lower carbon heating at Doncaster primary school


A


hybrid commercial heating system from Ideal Commercial Heating, featuring ECOMOD heat pumps and Evomax 2 boilers, has been installed at Hawthorn Primary School in Cantley, Doncaster, providing


a reliable, lower-carbon solution designed to improve comfort and efficiency across the site’s multiple buildings. Hawthorn Primary School is a co-educational primary academy with a


campus comprising several buildings of varying ages and construction types, creating challenges for consistent temperature control and system performance. The existing heating infrastructure, which consisted of two ageing open-flued boilers alongside undersized pipework, had struggled to meet demand efficiently, resulting in high gas consumption and unreliable comfort levels, particularly during colder months. To address these issues, long-standing Ideal Commercial Heating


customer Service 2 (HVAC) Limited was appointed to design and install a new system capable of delivering dependable year-round performance while reducing carbon emissions. The completed installation is a hybrid system combining two 50kW ECOMOD 290HT air source heat pumps with three wall-mounted Evomax 2 150kW commercial condensing boilers operating in cascade providing 450kW of output. The heat pumps are located externally adjacent to the plant room and


feed buffer vessels, while the Evomax 2 boilers are installed internally on an Ideal Heating frame and header kit with pre-formed insulation kits and a plate heat exchanger to ensure separation between the primary and secondary circuits. This configuration allows the heat pumps to satisfy the majority of the school’s heating and hot water demand throughout milder seasons, with the boilers automatically providing support during periods of lower external temperatures. A building management system (BMS) plays a central role in maximising


efficiency by intelligently selecting the most appropriate heat source depending on weather conditions and load requirements. This approach enables the school to maintain comfortable internal environments for pupils and staff while optimising energy use and running costs. As the project involved an existing education facility rather than a new- build, the system was designed to integrate with much of the original distribution infrastructure. Chris Snowden, Technical Operations Manager at Service 2 (HVAC) Limited, comments: “The benefit of using the ECOMOD 290HT heat pumps within the system is we can create up to 75°C hot water, which means you don’t have to change radiators. We can still run on the original system.” Fan coil units optimised for lower temperature operation were installed in selected areas to further enhance system performance. To provide separation between the primary and secondary circuits, preventing potential dirty system


water from circulating through the new equipment, an Ideal Heating plate heat exchanger (PHEX) was installed. Installation works included the construction of a dedicated concrete base and secure fencing for the


external heat pump units to meet health and safety requirements. Service 2 (HVAC) Limited also benefited from Ideal Commercial Heating’s free commissioning service


on both the heat pumps and boilers, which ensures correct configuration and automatically applies a five-year warranty.
